Photons have zero REST MASS, not zero total mass. Since photons
can never be found at rest, each photon has a nonzero total mass.

If you don't believe A. Einstein, read H. A. Lorentz.
Electromagnetic waves have a nonzero inertial mass. Particles have
mass associated with motion which can be explained by the force fields
the particles drag along. The idea of light being bent is merely an
application of the Law of Equivalence (Einstein's) to the concept of
electromagnetic mass (Lorentz). It sounds like you are knocking
Lorentz's idea, not Einstein's. Light is not massless in the way you
imply, and no modern physicists ever claimed it was so. You are
knocking a straw man.
Light has inertial mass, why is it a surprise that it should have
gravitational mass also? Some physicists restrict the word "mass" to
meaning "rest mass." Usually, there is a statement somewhere in their
articles or books referring to this distinction. If one can't read
entire books, and restricts oneself to sound bites, you may miss the
qualifier. However, the idea that "rest mass" is different from "total
mass" is squarely consistent with the work of H. A. Lorentz. Who, by
the way, never accused Einstein of stealing.
Since electromagnetic waves have inertial mass, it is pretty much
a trivial extrapolation to infer they have gravitational mass. If you
want, you can claim that A. Einstein made a trivial extrapolation from
the work of A. Lorentz. Some may think it unfair to Einstein, but it
would make more sense than your idiotic "massless photon" analogy. If
this doesn't work, you can try calling H. A. Lorentz an idiot.
We of ZOG respect the work of H. A. Lorentz. It was the Gestapo
that probably killed him. We ZOGites have established that Lorentz was
poisoned, he didn't die of a heart attack in 1934. Wasn't it
convenient Lorentz died as Hitler seized power? It didn't help the
Jews very much. Why are the Jews accused of stealing his work when it
was probably the Nazis that killed him?
